Today, I woke early (for me) only to lie down and fall back to sleep. In my sweatdamp slumber, I dreamt that we were at war with Epsilon Eridani, specifically its third planet, the only one in orbit around this orange sun to host any intelligent life. But when the aliens beamed down onto America’s streets, they turned into ISIS fighters, who had secretly built an underground tunnel from the Syrian city of Homs to Proxima Centauri. After that, the dream got weird.
